On Tuesday the president admitted there was evidence that chemical weapons had been used during Syria’s two-year conflict, but that it was not yet known how the chemical weapons were used, when they were used and who used them.

A defected general has confirmed that the Syrian government ordered the use of chemical weapons against the Free Syrian Army during select battles with Syrian regime forces.

The general, Zahir al-Sakit, told Al Arabiya that he disobeyed the orders and substituted the chemicals with disinfectant water he called “Javel water.”
